Truganina was primarily a wheat and hay growing and dairy farming area.
Hay making was a huge business at the time. Horses were the main form of transport and hay was their main 'fuel'.
One of the important local farming families at the time was the Leake family. William Leake pressed and exported 24 tonnes of hay a week and shipped to India. William and Alfred shared 3,400 acres of land — 1/2 used for hay , 1/2 for dairy farming. Their dairy (situated in what is now Rose Grange Estate between Leakes and Sayers Road) processed 400 lbs (182 kilos) of butter per week and about same of milk. Most of this used for butter and cheese.
Some of this was exported and earned the family a gold medal for their cheese.
The agricultural output of Truganina in the first half century of settlement was bigger than all the other agricultural areas of Victoria combined.
H.V. Mackay, inventor of the Combine Harvester and owner of Sunshine harvesters tested his machinery at Truganina.
William Leake bred rabbits on his property in order to provide shooting entertainment for Indian horse-dealers and hay buyers.
